PAPER-MAKING MACHINE.

Application filed Septe er 3 1.921.. Se ial No. 504,415.

To all 1071-0777 it may concern:

Be it known that I, RALPH S. CLARKE, a citizen of the United States,residing :at Walpole, in the county of Norfolk and State ofMassachusetts, have invented certain new and useful Improvements inPaper Making Machines, of which the following is arspecification.

This invention pertains to shower pipes for paper making machines.

The main object of the present invention is to provide a structurewherein the openings through which the spray water passes, may bereadily cleansed when for any reason they become clogged in whole orin-part, the arrangement being-such that a full normal spray may be hadthroughout the work ing length of the pip A further object of theinvention is to provide means whereby those portions of the openingswhich are normally closed and abnormally large may be exposed or openedso as to insure a flow of large volume through each and everyopeningwhereby any material which tends to clog such open ings iscarried out and the opening or openings thus cleansed. V

A further object of the invention is'to provide means exterior of thepipe to close the abnormally large portion of the open ings, suchclosure devices preferably being formed integral with the deflectorswhich cause the jets issuing from the restricted portions of theopenings to take a fan-shape and thus produce a continuous spray fromone end to the other of the pipe.

The invention is shown in the accompany ing drawings, wherein,.v

Fig. 1 is a side elevation of the spray pipe with movable deflectors.mounted there- Fig. 2 a similar view of a portion of the pipe upon anenlarged scale;

Fig. 3 a transverse vertical sectional View on the line III III- of Fig.2;

Fig. 4 a like view on the line IV-IV of Fig. 2;

Fig. 5 a view similar to Fig. 2 showing the combined deflectors andclosures shifted laterally to fully expose the openings one of saiddeflector-s being shown in section; and

Fig. 6. a detail perspective View of the actuating bar, one of theguides or supports therefor, and one of the deflectors and its alliedparts.

In the drawings, 1 denotesa pipe closed" atone endand adapted to beconnected at 1ts opposlte end to the source of supply of water to beemployed in the shower. The

pipe. is provided with a series of openings 2 (Figs. 4t and 5) which, aswill be seen, are oval in form, the smaller end of each open-' ing beingdesigned to be. exposed at all times and through-Which smaller exposedportion i, the rod at one end having'a link 5 secured thereto,- theopposite end of the link being attached to an actuating lever 6fulcrumed upon a bracket 7 secured to the pipe or to a fixed portion ofthe machine.

.lVllounted adjacent each of the openings and designed to be moved intooperative relation therewith by the'rod 3 is a combined closure anddeflector. Inasmuch as theyare each alike in form a description of onewill sufiice for all. As will be best seen upon reference to Figs. .4and 6, the closure element takes the form of an 'arcuate plate 8 whichconforms to the outer face of the pipe and is made suffieiently long togive a fair bearing upon the pipe. It eirtends for wardly tosuch anextent. that it overlaps the rear larger portion of the opening-:2 whenit is moved to'the position shown in Figs. 1 and 2, leaving the smallerend of the opening exposed,- the rear or larger portion being closedoff, as best indicated in Fig. 4;. Extending outward from theforwardportion of the closure element 8. is a deflector plate 9 set atan angle so thatthe water passing from thesmaller end of the openingcontacts the same and isspread out so that the conjoint spread jets formin effeeta sheet spray from one end of the pipe to the other. i It isnot necessary, however, that the'sprays formed by eachopening absolutelymerge or join ifthe pipe is provided with means for endwisereciprocation, as, for instance-ms shown in the construction in Letters.Patent to Charles S.- Bird, No.7 1,355 159.72, datedJune 14., 1921.Extending upwardlyfrom the closure element 8 is a yoke or bail shapedmember 10 which passes about the rod 3. A spring 11 is seated with- '65the water passes while the machine is in in the yoke, hearing at itslower end upon the face of the closure element and against a plate orwasher 12 interposed between the upper end of the spring and the" rod. 7

From this construction it will be seen that the closure element is heldin close contact with the surface of the pipe. Secured to the rodto'each side of the yoke-shaped member 10 are arms 13 and 14, respectively.The lower ends of these arms, .or-more specifically the inwardlyprojecting fingers 15 formed thereon, bear against the sides of theclosure elements 8 and consequently as the rod 3 is shifted the variouscombined closure and deflector plates are likewise moved therewith.

WVith the parts in the position shown-in Fig. 1 the large rear portionof thefopenings are closed off and the deflectors 9 stand. in alineinentwith the forward restricted portion of the openings 2, and the waterpassing from such restricted openings contacts the deflectors andis-thrown outwardly against the screen or. felt in the form of a spray.When it becomes necessary to clean the openings, as they sometimesbecome clogged with fibers and other foreign matter, it isaonlynecessary that the operator actuate the handle 6 and thus :shift the rod3 longitudinally, whereby the combined cover and deflector elements aremoved from the position shown in Figs. 1 and 2 to the osition shown in Fig. 5, whereupon the ull area jofthe opening is exposed, allowing thewater to surge through the same and carry out'any extraneous matterwhich is lodged in the openings. 1

The construction is advantageous over those which have heretofore beenproposed wherein a cleaner was located wlthin the pipe, such, forinstance, as a piston ring ear-' ried by api'ston and moved back andforth through the pipe with a view of disturbing any material lodgedover or ,in the holes under the deflectors. Such arrangement issatisfactory up to acertain point, but wnere it is sought to employwhite-water or water whichhas been used in the mill and which hasthelargest part offibers removed but still contains asmall amount offiber, filler,

etc., it is found that'such internal arrangements are not whollysatisfactory. With the openings as will wash out any fiber that adheresto thewalls ,of'the smaller portion of the openings.

Whatis claimed is V 1. The combination with a pipe having a series ofoval-shaped openings therein, of means shiftable longitudinally, of thepipe for coveringthe larger portion of each of said openings. 7

2. The combination with a pipe having a series of oval-shaped openingstherein, of a combined closure and deflector for each opening; andmeansfor positioning such element above each of said-openings forclosing ofi the rear larger portion of' each opening and positioningthedeflector-in line with the restricted exposed portion of said pening l J3. In combination with a pipe havinga series of openings therein soformed as to be narrower at one portion thanat the other; I

a series of combined deflectors and closures one for each opening, saidmembers being so formed that when positioned respectively with referenceto" the openings the larger portion of the opening will-be closed andthedeflector brought into position with ref erence to the smaller exposedportion; and

-means for moving saidelements longitudinally of the pipe over and awayfromthe larger portions of said openings.

4. In combination with a pipe "having a series of substantiallyoval-shaped openings formed therein; a rod extending along the pipe inspacedrelation thereto; means formoving the rod endwise'; a combinedclo'sure" and deflector for each opening, the closure being such as toblank off the-largerf area of the opening leaving the narrower portionthereof exposed and in line with the deflector; and'means carried'by therod for engaging the closure 7 elements to. movethe same as the rod ismoved. V

5. In combination with a pipe havinga series of openings formedtherein;a rod extending lengthwise of the pipe in spaced relation thereto; acombined closure and deflector for each opening; a spring interposedbetween the rod and the closure element tohold the same to? its seatuponthe to shift thecombined closurefand deflector as the rod is'movedendwi'se; r V

6. In combination'with a pipe havinga plurality of openingsformed'therein; a rod located to one side of and-shiftable lorigi tudinallythereof; anda plurality of compipe; and means cooperating-with the rodbined closure and deflector elements mov able with the rod, said closureelements when brought into position with reference to the openingsserving to restrict the same and to permit a relatively small jet onlyto be passed outwardly through the openings into impingement with thedeflectors.

7 In combin tion wit a p pe having a" plurality of openings formedtherein; a rod extending along the pipe adjacent said openings in spacedrelation to the pipe; means for shiftng the rod longitudinally; aplurality of combined closures and deflectors, one for each opening,said closures when positioned over the openings closing ofl the majorportion of the openings and restricting the same so that a small jetonly may pass therefrom into contact with the deflectors; and meanscarried by the rod for moving the deflectors.

8. In combination with a pipe having a series of jet openings formedtherein; a rod extending lengthwise of the pipe in spaced relationthereto; a series of combined closure and deflector elements, one foreach opening; a spring for each of said members serving to hold theclosure element seated upon the pipe; and a pair of arms secured to therod upon opposite sides of each of the combined closure and deflectorelements and serving, as the rod is moved endwise to carry thedeflectors to and from position with respect to the openings.

In testimony whereof I have signed my name to this specification.

RALPH SWAN CLARKE.
